Google owned Fitbit is starting to roll out the blood oxygen sensor to help with sleep apnea diagnosis. Seems this together with Rap would be match made in heaven, I do remember reading somewhere that having this improved the accuracy of Raps diagnosis. I can't remember where I read it,. Maybe someone with a better memory will know. A partnership is looking pretty valuable at the moment.
